But how do I use neon? I tried
my-laptop ~ $ ./configure --with-apr=/usr/bin/apr-config
--with-apr-util=/usr/bin/apu-config --with-apxs="/usr/bin/apxs2"
--disable-mod-activation --enable-maintainer-mode --with-ssl.

But that doesn't work, http/https scheme is missing. How do I get
neon, it doesn't seem to be installed on my machine. I tried sudo
apt-get install libneon27-dev but with the same result.
